Overcoming Self-Doubt

Hello Beautiful Thinkers,

I’ve just finished The Wonderful Wizard of Oz. It’s been on my list of books to read for such a long time but I’m sure you all know how those list can be. Just like in the movie the problems of the main characters (with the exception of Dorothy) stem from self-doubt. The Tin Woodsman, the Scarecrow, and the Cowardly Lion had the thing they desired in them the whole time which is apparent from their actions as we read. Take inspiration from these characters and write one of your own that is plagued by self-doubt. Who or what helps them to overcome this problem?
